The sound wave generated by these sources transfer its energy throughout the duct and to the occupant's area as shown below. Tougher local codes are cracking down on high sound levels. Acoustic silencers and attenuators are used in industrial processes to reduce the noises transmitted via ducted or piped systems, and to achieve an acceptable noise level within industrial premises. This type is largely dependent on area change to reflect sound energy back to the source and utilizes the attenuation properties of expansion chambers and perforated tubes. Figure 18: T60 decay time. The test procedure involves a sound source fed to loudspeakers in the source room being measured in both the Source and Receiver rooms, and the measurement of Reverberation Times in the Receiver room. sound attenuators are suitable for DW 142 class C applications. If the unit was lined with 100mm thick material that figure would be uniform. Thanks, builder49. This will keep the sound from passing through the wall, but will make for a very echo filled room.
